I bought HP EliteBook 840 G1 (H5G23EA), disconnected RAID of standard HDD and mSATA SSD in "Intel® Matrix Storage ManagerOption ROM" (http://download.intel.com/support/chipsets/rste/sb/intelr_rste_linux.pdf page 26) (entered by Ctrl+i shortcut after POST). After that I can't enter this "Intel® Matrix Storage ManagerOption ROM" any more.
I have selected 'RAID' disk mode and 'Promt Ctrl-i' in BIOS.
Any ideas how to recreate the RAID (pair HDD and caching SSD)?

I contacted local HP phone support. They told me, that this is a "feature". In order to get your "Matrix Storage ManagerOption ROM" running again you have to install windows system and Intel Rapid Storage Driver (and of course all necessary HP drives). Such installatin magically reenable "Matrix Storage ManagerOption ROM". They weren't able to explain how and why. The admitted that the "Matrix Storage ManagerOption ROM" is pretty useless because you can manage your RAID more comfortably from Windows RST manager.
I haven't tested these steps.

You can re-enable this menu by doing the following: create WinPE boot image with Intel Rapid Storage Technology driver and RSTCLI.exe (or RSTCLI64.exe) tool from Intel.com. Driver and tool versions need to be the same, e.g. 12.8. Now boot into WinPE, run the tool and type the following commands:
rstcli -M -Z (wipes the array information)
rstcli --accelerate --createCache --SSD 0-1-0-0 --cache-size 30 (creates cache on SSD)
rstcli --accelerate --setAccelConfig --disk-to-accel 0-0-0-0 --mode enhanced (accelerates the HDD)
Check the correct parameters according to your hardware and preference for the mode.
Now reboot and you'll see the OROM again. I hope this helps!

I faced a similar problem, and OKampman's post really help.
I have an elitebook 840 G1 in hand. After I format the 30Gb SSD, the 'Intel Rapid Storage Technology Option ROM' is gone and never back even if the 'RAID SATA Controller' and 'ctrl+I prompt' are checked in bios. I install windows8(x64) and IRST, no accelerate function found in IRST UI console, and SSD can be seen as 'pass through' in disk manager.
Here is how the problem solved:
1) download your IRST dirver version matched 'Intel® Rapid Storage Technology Command Line Interface (RST CLI)' at http://downloadcenter.intel.com;
2) read 184.108.40.206 of 'Intel SRT Enterprise Deployment Guide Rev 2.0.pdf' as attached, learn how to enable IRST after the OS is installed by using the RSTCLI tool.
Hope this help.

I needed to install an alternate disk in my laptop, but after re-installing my original disk, the cache/raid config was gone.
I've managed to reconfigure the cache/raid configurations, through Intel RST cli, but now I cannot start my Windows operating system!
I get an error saying "A required device isn't connected or can't be accessed".
Can anyone point me the right direction... Or have I just lost everything?

Working reinstall procedure:
Step 1 reinstall OS:
- take the hdd and reinstall easily in a desktop computer (cdrom etc) in AHCI mode.
- re-insert in the laptop and run in AHCI mode
At this point you have 2 separate drives - sata hdd and ssd
Step 2 re-enable the SSD cache:
Change from AHCI to RAID:
Change to RAID mode from AHCI mode or IDE mode:Warning: Spoiler! (Click to hide)
- Exit all Windows-based programs.
- Press [Win] + R or take the RUN option from the start menu.
- Now type regedit there and press Enter Key to open up the Registry Editor Window.
- If you receive the User Account Control dialog box, click Continue.
- Locate and then click the following registry subkeys:Code:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\iaStorV HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\iaStor
- In the right pane, right-click Start in the Name column, and then click Modify.
- In the Value data box, type 0 [3 is default], and then click OK.
- On the File menu, click Exit to close Registry Editor.
- Restart your computer
- Go to UEFI/BIOS and enable RAID, Save & Reboot
- Another restart will be required to finish the driver installation.
After reboot in device manager AHCI controller is replaced by RAID controller.
Reinstall Intel RST driver.
Delete any existing partition on SSD.
Start RST GUI - now you have the option to create the RAID.

ybalabanov's answer is 100% correct!! The HDD in this Gen 1 Elitebook 840 died and I replaced it. Mode was AHCI in the bios by default so I left it this way before installing windows. The Intel Rapid Storage app wouldn't show accelerate as an option. Uninstall it first and follow ybalabanov's instructions. I only had iaStorV and msahci but no iaStor, so I only changed those two.
After installing windows I would recommend to use diskpart to do a "clean" on the mSATA device before switching to RAID, just for good measure:
1. Open start menu, type "diskpart" and press enter
2. Press Yes
3. Type "list disk" and press enter
4. Type "select disk #" where # is the number it says beside the mSATA device (the one thats 31GB, not the HDD which would be hundreds of GB
5. Type "clean" and press enter
6. Type "exit" and press enter
7. Open start menu, type "partitions" and click on the one called "create and format hard disk partitions"
8. It should automatically ask you to initialize the new disk. Just press ok. If it doesn't, right click the Disk that says "not initialized" and press initialize and press ok. Close the partition manager window.
Then continue with changing the registry, switching to RAID in bios, start windows, restart again, install the latest intel RST software, and finally enable acceleration. It is much much faster to start windows and load programs right after. Jusst make sure that every time it asks you to reboot, wait a minute and then do it before continuing.
